Nitrogen and sulfur interaction on nutrient use efficiencies and diagnostic tools in maize
(Elsevier, 2020-05)
Nitrogen (N) and sulfur (S) critical dilution curves and the N:S stoichiometry are useful tools for evaluating nutrient status in maize (Zea mays L.). Nutrient supply for both N and S impact plant nutrient uptake, consequently ...
Can savannas become forests? A coupled analysis of nutrient stocks and fire thresholds in central Brazil
(2013-07-26)
Aims: The effects of fire ensure that large areas of the seasonal tropics are maintained as savannas. The advance of forests into these areas depends on shifts in species composition and the presence of sufficient nutrients. ...

Sheep faeces decomposition and nutrient release across an environmental gradient in Southern PatagoniaDescomposición y liberación de nutrientes de heces de oveja en un gradiente ambiental en la Patagonia austral
(Asociación Argentina de Ecología, 2017-02)
La mayor parte de la tierra en la Patagonia austral está dedicada a la actividad ganadera ovina extensiva, desde la cordillera al mar, en condiciones ambientales contrastantes. Hay estimaciones que indican que en ecosistemas ...
Water and nutrient supply for desert food webs: from autotrophs to top consumers within the framework of ecological stoichiómetry.
(2007)
Energy and material flow are essential to ecosystem functioning. Transfer of energy and
nutrients within ecosystems is best described in terms of food web interactions among taxa
in ecological comrnunities. Energy and ...
Decomposition of and nutrient dynamics in leaf litter and roots of Poa ligularis and Stipa gyneriodes
(Academic Press Ltd-elsevier Science Ltd, 2003-11)
A field experiment was conducted in a temperate semi-arid grassland of central Argentina to determine mass loss and P and N concentrations of decaying leaf litter and roots of Poa ligularis (high-quality litter) and Stipa ...
Hydro-biogeochemical processes in Greenland Ice Sheet catchments: nutrient dynamics, chemical weathering and wider impactsHydro-biógeochemical processes in greenland ice sheet catchments: nutrient dynamics, chemical weathering and wider impacts
(2017)
Global warming has led to significant increases in melt rates of the Greenland Ice Sheet (GrIS)
and runoff since the beginning of 1990, and the GrIS is expected to be a major contributor to
global sea level rise in the ...
